Tools & Capabilities Breakdown

Celestrak Tools (0)

No explicit tool names declared in metadata yet. Check project README on main listing page.

Tle Tools (3)

get_tle

Fetch the Two-Line Element (TLE) set for a specific satellite by its NORAD catalog ID. Returns the satellite name, epoch date, and both TLE lines.

search_satellites

Search for satellites by name or keyword. Returns matching satellites with their NORAD IDs and TLE data.

list_recent

List the newest satellites in the NORAD catalog, highest catalog number first. NORAD ids are assigned in roughly launch order, so this approximates most-recently-launched. Note this orders by catalog entry, not by TLE epoch — the upstream offers no epoch-date sort.
